What is the formula for Vernier Caliper?

Answer: In case of a vernier caliper, it’s the least count’s formula is given by the formula provided below. 

Vernier caliper’s least count = the smallest reading within main scale/ Number of divisions within vernier scale = 1 mm ÷ 10 divisions = 0.1 mm.

The object’s length is determined using Length = (VSR * LC) + MSR where 

MSR: reading of main scale

VSR: reading of vernier scale

LC: Least count
